The ETS Lindgren EMCO HI-4455 Isotropic Field Probe is a battery-operated broadband Isotropic Electric Field Probe designed for use in making RF exposure measurements in the vicinity of broadcast facilities and industrial RF sources.
This probe uses optical isolation to minimize field perturbation during measurements. The HI-4455 Broadband Isotropic Electric Field Probe utilizes a microprocessor for intelligent operation and control. The probe's self-contained power supply employs a 3.6 VDC NiCd battery, which provides up to 17 hours of continuous operation.
The HI-4455 measures the field strength in each of three axes. It performs a vector addition calculation on the readings and sends theresultant to the receiver via a fiber optic cable.
Applications include: Health and Safety monitoring, measuring microwave transmitters and antennas, EMI monitoring, and measuring the fields generated by ISM equipment.
